To all 'whom it may concern.'

Beit known that I, FERDTNAND G. HENRY, a citizen of the United States.residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inSignals; and I do heieby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to signals for vehicles and particularly, thoughnot exclusively, to signals for use with automobiles to indicate fromthe rear or other parts of the automobile the direction in which theautomobile is to turn.

A further object of the invention is to provide an electrically operatedsemaphore with means adjacent to the operator for setting the semaphoreeither to the right or left, or to a vertical to indicate respectivelyright and left turns and stops.

A- further object of the invention is to provide improved means forrendering the y. signals visible both by night and by day.

A further object of the invention is to provide improved means fordetermining rom the position of the operator Whether or not the signalsare properly set.

A further object of the invention is to provide .improved means bothmanual and automatic for releasing the mechanism to return to normalafter a corner has been passed either hij making the turn or byneglecting to maKe the turn.

A further object of the invention is to provide a system of lightsshowing a predetermined color,\ the co or of one of which is changed bythe movement of semaphore to any of the aforesaid positions incombination With a system .of lights visibleto the operator, showingsimilar colors.

With theseand other objects in view the invention consists in certainnovel. features of construction, combination and arrange- `ment of partsas will be hereinafter more fully/described and claimed.

The improved signaling device which forms the subject matter of thisapplication comprises a housing 50 containing a4 motor l having a shaft52 carrying a Worm 53. Intergeared with the Worin 53 is a gear Wheel 54carried rigidly upon the hub 55 free vto rotate upon the sleeve 56formed 1 rigid and preferably integral With the housing and moreespecially that part of the housing shown at 57 asthe cover or closure.Through the latter sleeve extends a spindle 67, being seat-odin a boss59 and engaging the rear of the" housing as at 60 forming a journal `forseveral arts hereinafter mentioned.. Through spindle 67 extends a stud58 being screwed rigidly into the rear of the housing 5G forming asupport for the signal bell 61. The gear 54 is provided with a flange 62carrying an internal 4gear 63.

Mroiinted also upon the spindle 67 is a spider 64. Upon` the spider 64is journaled a pinion 65 intermeshing With the internal gear 63 at oneside and at its opposite side with a gear 66 journaled upon the boss 59.Ihe spider 64 is mounted rigidly upon the s' indie 67 to which is alsorigidly secure-d tr el hub 68 of the semaphore 69, so that the spider 64and the semaphore 69 move always in unison;

The 'Weight of the semaphore 69 tends to hold the s ider 64 normally inthe position shown at liig. 1, and it is obvious that as `the ears .54and 63 are rotated'by the motor mlt eidler geait65 will cause the gear66 to rotate. It is also obvious that if ineaiis isfyprovided forAconnecting the spiderff64 with the gear 66 the spider 'and semaphorewillrotate therewith. Such means is provided in the detent 70, shownparticularly at vFig. 8, being pivotcd to the spider at 71 and heldyielding y in position by a spring 72 spanning the interval between-thedetent and the latch 7 2, the latter bein also pivoted to the spider'at73. VVhcii tie spider 64 and gear 66 are locked together by the detent70 as shown at Fig. 8, it is obvious that both will rotate togetherunder the impulse of the motor 51 and tinue suc ...rotation until ltheroller 74 engages the poi't 75 of the cam 76 when rotatiiigin 4oneclimatica or by the cam extremity 7V of the core 78 ofV solenoid 79.wien the datent V701is1thns disen Y aged from the gear "66 itisxlatchedj in such isenv gaged position by the latch 72 engaging in therear of the finger 80 carried by such detent 70. When so unlatched thegear 66 and Spider 64 are disen aged and either may rotate independentlyo the other.

The spider `64 also carries pins 81. and 82 positioned to be` engaged bythe latch 83 when the spider rotates in either direction,`

the saidA latch 83 being held resiliently to en* gaging position by thcspring 84 attached to the opposite leg of the latch 83. Armature 85 isprovided controlled by in electromagnet 86 and spring 87 carrying a pin88 extending across the latch 83 so that when the armature 85 isattracted by the rnagnet 86 the pin 88 depresses the latch 83 againstthe tension of the spring 84.

It will be noted especially from Figs. 3 and 11 that there are twoelectro-magnets in juxtaposition, the other clectro-inagnet 89 actingupon the armature 90 which carries a pin 91 also bearing upon the hitch83 and a switch arm 92, the use and olieratioii of which will behereinafter described iii relation to the electric circuit.

A second latch 93 is also mounted adjaent the latch 83, but as will benoted from 4 ig. 12, normally positioned with its latching extremityabove the latcliing extremity of the latch 83. Like the latch 83 thelatchl 93 is also controlled by the pin 88 carried Aby the armature 85.The latch 93 is also controlled by a spring 94- holding it yieldingly toposition.

'llie spider 64.carrie's a pin 95 which, as will be noted from Fig. 12,describes a cir cuinfei'ence less in diameter than the circumferencedescribed by the pins 81 and 82. As will be noted also from Fig. 13, thepins 8l and 82 are of such length as not to engage the latch 93 but toengage the latch 83, while the pin 95 is positioned to be engaged by thelatch 93, but to pass over the latch 83 Without engagement.'

Vl-Yhen, therefore, the spider 64 is rotated by the motor ashereinbefore described such rotation Will continue until either the pin81 or 82 has been engaged in the notch of the latch 83 depending uponthe direction of rotation, v'and simultaneously ythe roller 74 of thedetent 70 will engage the cam extremity or the cam point 77 and releasesuch detent from engagement With the gear 66, whereby the gear 66 isfree to rotate under the momentum of motor but without af fectin therotation of the spider and the sema ore 69 which are held in such lockedosition by the latch 83.' When the detent 0 has been raised out ofengagement with the gear 66 by engagement-with the cam as stated, thelatch 72 willengage back of the nger and hold 'such detentinl releasedposition until the spider has' been returned the latch 83 and under theweight of the semaphore 69 the parts will be returned to normal. Whenthey reach the normal position the roller 9G upon the latch 72 willenage the cam 97 to discngagc such latch gironi the linger whereupon thespring 7 2 will return the detent 70 to locking position, and the partswill be held in position :for a second cycle of operation. The manner ciactuating the several parts electrically will be described hereinafterin relation to the electric circuits.

When it is desired to set the semaphore at a vertical or stop positionit is necessary to turn the spider one-half a revolution and until thepin is engaged by the latch 93. To accomplish this it is necessary thatthe roller 74 ass by the cam obstruction 77 to accomplish which thesolenoid 79 is energized to draw the core`77 and remove the camobstruction from the path of movement of the rollerA 74. Then this isaccomplished the motor continues to operate until the pin 95 is engagedin the notch of the latch 93 and simultaneously the roller 74 of thedetent 70 engages the cam extremity 98, the remaining movements and thereturn being the same as when the semaphore is set at either side to'indicate a turn.

While the turning of the semaphore 69 to right or left will indicate aturn to either right or left direction it is obvious that such signalwill be visible only in the light and that signals for the dark arenecessary. To provide such signals lamps 99 and 100 are provided onopposite sides of the housing 50 with a third lamp 101 located upon thetop of the housing. The semaphore is also provided with a transparentdisk 102 positioned to swing over and cover either of the lamps 99, or101 as occasion may require. The transparent disk of the semaphore willbe of a color differing from the colors of the lamps 99, 100 and 101,and for the purposes of 'illustration only it may be assumed that thecolor of thelamps is white and the color of the disk green. It will beobvious, therefore. that under inormal conditions two white lights willbe exhibited, but that when the semaphore is Iswung to eithe'r turnposition one of the side lights will respectively be` coveredand willshow green, and when swung to istop" position the top light "101 will belighted and show green. When the right light shows green and the otherwhite it will be understood that the turn is f to be Iliade to theright, the reverse being lamps are each preferably surrounded by aparabolical reflector 103 with a disk or lens 104 held in position by agland or bezel 105 with a sprln 106 ."to hold the refiector against thedisk 104, and to prevent rattling-all of which i's more plainlydisclosed at Figs. 2 and 3.

. To the back of the housing in the rear of the spider 64 is attached aninsulating backing 106 as shown more particularly at Fig. 2, and thereonaremounted electrical contact segments 107 108, 109 and 110 adjacent andin circumferential alinement with which are contacts 111, 112, 113, 114,and 110. The spider 64 also carries spaced brushes 117 and 118 slidablyinserted through openings 119 and 120 as shown more particularly at Fig.11 and held yieldingly in engagement with the contact strips or contactsabove referred to by the spring 121.

Insulating material 106' also carries conH tact segments 122 and 123,Fig. 19 while the spider carries a brush 124 inserted through a hole 125in the spider as shown at Fig. 11, and controlled by a spring 126` bywhich sa'd contact brush 124 is held yieldingly in po ition to engagethe contact strips 122 and 123 when the spider is rotated to the properposition.

Fixedalso to the s ider is a pin 127 po- 95 sitioned to engage either ofthe contact sprlngs 128 or 129 as the spider is rotated in eitherdirection to force such springs into engagement with contacts 130 and131 which. are electrically connected in the system as will behereinafter more fully described.

For properly sounding the alarm an electrical bell mechanism 132 Fig. 2of substantially the usual and ordinary construction is provided, theelectrical circuit for controlling which will be hereinafter more fullydescribed. Also an electrp-magnetic switch mechanism is providedconsisting of the magnets 133 and 134 With their respective armatures135 and 136 with a spring y137 spanning the interval between the twoarmatures and tending to hold ,them yieldingly away from the cores oftheir respective magnets. Interposed between the magnets 133 and `134are contact posts 138, 139, and 141. The armature 135 is provided with aswitch blade 142 adapted to oscillate between the con tacts 138 arid 139as the armatureis moved, While the armature 136 is provided with asimilar switch blade 143 adapted to oscillate between the contacts 140'and 141. The armature 135 also carries a switch blade 144 adapted toengage the contact 145 while the armature 136 carries a switch blade146l adapted to engage the contact 147. The pivots 148 and 149 of the,armatures are also employed as binding posts to receive the Wiring ofthe electric circuit as will be hereinafter more fully described. Thecontacts 188 and 140 are electrically connected by a strip 150, whilethe contacts 139 and 141 are similarly electrically connected by a strip150'. rllic entire switch mechanism above described is mounted on aninsulating baclf-- ing 151l secured within the casing 5t). Theinsulating hacking 151 also carries binding posts'A, B, (l, D, E, F,which serve to connect thc Wires of the several circuits as will behereinafter more fully described.

For providing un automatic return of the seniaphorc to norinul when setyeither at a .turn position or a stop position attachment is made withthe steering gear of the vehic e so that when u turn is made aftersetting the apparatus the semaphore will be rclcuscd to return tonormal. Such autoY math'` mechanism is `shown in perspective at Fig. (lund in detail at Figs. 16 and 17, It ctnnpriscs a housing 151 attachedrigidly to the steering colulnu 152 und :i cani member 158 rigidlyattached to the steering shaft 151 and rotating therewith The caniinem-- ber 15% is provided with cuius li und 1?1 which engage a roller157 carried upon t lever 158 pivoted :it 158. The lever 158 is providedwith perpendicular oll'set portions 160 and 161 bearing uponspring-presseal plungers 162 and 168 respectively. The shape andposition of the cams 155 and 15G ns will he apparent more especially atFig, 17 is such that as the cam member 153 rotetes with the steeringshaft 1511 the roller 157 ind lever 158 will be forced toward thesteering lever (the dotted line position shown at Fig. 16) until theends of the come pass beyond the roller when the spring-pressed plunger162 will throw the. lever bach to norninl. Upon the return movement ofthe steering shaft 151 the roller 157 will be enI gnged upon theopposite sides of the cani 155 to throw such lever to the broken lineposition shown at Fig. 16 to dcpressthe springpressed plunger 163 andengaging l n I against the contact spring 1611 force such spring overagainst the Contact 165 to close the circuit, 'for the purposeshereinafter described.

It is desirable that the operator, will be able at all times Vto detectwhether or not and in what manner his signals are set,.for which purposea. tell-tale is provided es Shown in perspective et Fig. 18. Thetelltale comprises a housing 166 having deep holes or Wells 167, 168,169 and 170 having lamps located therein as shown in the diegrammaticvewFig. 24. To correspond with the color scheme hereinbeforc mentionedit is desirable that one of the telltale lights as 168 shall be white`while the remainder of the lights 167, 169 end 170 shall be green. Thecontrol sind function of the several lights will be hereinafter morefully, described in.r connection with the dcscription of the wiringandelectric circuits.

The telltale will be located on thcdash of the automobile, or in suchconvenient po sition as may be found desirable, and owing to the depthof thc holes thc lights will at times be located in scini-dorlmcss undwill bc visible cron in duylight to the opcrutor.

The control of thc several parts above described is preferablyaccomplished electrically, for which purpose a. source of elec tricnlenergy .is employed here designated at 171 and called a buttery forconvenience, it` being undcrstooil of course thatI any coin venient undavailable source of electrical energy may be suliistituted. lt will alsobe understood that :i number of different but terios for thc severalcircuits may be subW stituted within the lnniwlcdge of a skilledelectrician.

.tirs explained in relation to the lighting, at iill times duringdarkness the two lights. 99 and 10U will bc lighted. A switch 17:24 isshown diegranunnticnlly in the circuit at Fig. 24 for controlling theselights. lVhcn the switch is closed the lighting circuit ns follows:Front buttery 171 through line 176 to switch 172, line 174 to point 175to point 176 through tellftalek light 168, line 177 to lamp 91%, line178 to lamp 100, lines 171'. 18() und 181 to binding post A, and lines182 :lud 183 buck tothe buttery 171. 1t will thus he seen that telltalelight itt is iu serios with lights 9S) und TO()- The stop l light` 101und lts telhtiile i7() nre lighted only when the switch S is closed.

'The lighting of these lamps 101 and 1701s accomplished in this manner.Current from the battery 171 passes through the line 17 8, switch 172,line 174 to 175, line 184 to tell tale 170, line 185 to contact strip122, and when the interval between the Contact strips 122 and 123 isbridged by the brush 124 the current passes from the contact 'strip 123to the line 186 to the lamp 101, and lines 187 and 188 and 183 tobattery. The telltale light 167 is lighted only when a. turn is to bemade to the ri ht as follows: From battery 171 to line 1 3 switch 172,line 174 to 175 to 176, line 189 to tell-tale 167, line 190 to contact131 through contact spring 129 sind contact plate 191-to line 192, 188to 183 to battery. The contact spring 129 `is in contact with contact131 only when the pin 127 has rottcd one-fourth of a revolution to forcesuch spring downwardly into engagement with the contact. Likewlse thetelltale 169 is livhted only whenV a turn is to bemiide to .thebleft asfollows:

When the semaphore has been set to indicate a right turn thebrush 117" Vhas lpassed olf of the contact strips 107 and 108 and is inengagement with the contacts 113 and 114. If, now, the switch N is#rinsed the latch S3 will release the pin in the following manner:Current 'from 171 Hows through lines 231 and it' to Contact 253, throughlines El :mit to binding postJ Ffthrough line *$.36 to eo toet 114. ylitwill be recalled that thcn 117 is now spanning the intervat t thecontacts .113 and 11-1 so that A; rent, Hows across said brush 117 i tomagnet 86, through Q05, 206 and to lines 203, 202 and 221 to 138 thrtn210, 180 and 181 to binding post, 182 and 183 tohatteiy. This will imagnet- 86 attracting armature the tension of spring 87, depressingnnund. therewith latch S3 which is in ongegeincnt with pin 81. releasingpin 81 so that the weight of the semaphore arm may re turn the parts tonormal. It will he rel memberetl that thc spider 64 Carrying thesemaphore arm and the gear' 66 are independent of each other at thisoint by reeson of the datent 70 being he d out of engagement by thelatch TEL-but that when it. is returned to normal the roller 96 is deof;pressed by the cam 97 to unlatch the latch 752 and permit the detent 70tomfall into engagement with the gear (i6, thereby looking i the lpnrtsin initial position. When he 1G@ is sniilar except that current passingthe swi 'h N passes to contact 258, line 259 to hiniling post G. throughlinerQtf) to Contact 111. across brush 117 to contact 112, through lines261, 262` 263 nl Z6-.t to the magnet Si?, the remaining action beingequivalent in all respects to the action when the Sem'n/ phorc is setrat right turn.

Tf the semaphore is set 'zit stop signal it is rcleae-icd to return tolnormal by nctunt? ing the switch N which action is exactly 'the salmeas restoring to normal when gt at the right turn position.y thecnergizir r of the magnet 13 depressing the latch 3 antl rv .lensing thepin lhetsanic :is depressing the 1 hitch 83 rch-ases tho pin 81. It willhe un ilerstootl, however, that when he Signal is set at stop the magnetStlbcing energized thc latch S3 wiil remain in depression posiY tion topermit the passage both waysA of the )in 81, such depression beinaccomplished hy the pin 91 hearing upon telateh 83 and maintaining suchlatch 1n depressed position so long as the magnet S9 is energized irrt'-spcctive of the position of the pin S8.

Then the semaphore is sot at any of the aforesaid turn positions it isdesired to rem tur-n them to normal automatically by the act of turningthe corner designated. For this purpose the Contact spring 164 is closedagainst the contact 165 as hereinbefore described, the current thenflowing from the battery 171 through lines 231, 173 to point to 100,through line 205 to spring 164 to contact 105, line-260 to binding postE, through line 267 to point 208, through lines 202, 203 and 204 tomagnet 86, through lines 205, 200, 270 to strip 107 through lines 203,202 and 221 to )oint 138, through lines 210, 180, 181 to binding post A.and through lines 182 and 183 to battery. This energlzes the magnet 80the same as closing the switch N whereby the spider is automaticallyreleased to permit the semaphore to'return to normal. i

It will also be noted that when magnet 80 .is energized the Contactstrip 108 is electrically connected to the strip 110 through the line250 to contact 239 to contact 238 through line 271, to contact strip110, and contact vstri p 107 4is also electrically connect ed to strip109 through line 270 to contact 210 to contact 241, and through line 269to contact strip 109. i

Provision must be made also for the contingency arisin from the operatorhaving set the signal or a turn and passing the corner Without making aturn desires to make a turn at a subsequentI cornera If the subsequentturn is to be made in thesame direction, it` is obvious that by closingthe same switch no action will result, but if the turn is to be -made inthe opposite direction it is necessary that revision be made forswinging the semap ore through half its circumference to the oppositedirection.

By closing switch L to make the left turn, therefore, current will flowfrom the hat tery 171 through the lines 231, 173, 213 to contact 214,through, the switch L to contact 272, through the line 273 and 255 tobinding post F, through line 256 to contact 114, across brush 117 thenlocated in that position to contact 11-3, through lines 251 and 264 tomagnet' 86, through lines 206 and 270 to 107, to lines 203, 202V and 221to` oint 138, through lines 210, 180 and 181 to binding post A, andthrough lines 182 and 183 to battery. This will energize the magnet 86and attract the armature 85 to de ress the latch 83 and release thespider 64. As soon as the brush 117 has moved o' of the contacts 113 and'114 the circuit to the magnet 86 is broken, so that the latch 83 isreturned to normal, but immediately on passing oft of contacts 113 and114 the brush 117 short. circuits the contact strips 107 and 108. Thisthrows the magnet 134 into circuit as follows: Current from the battery171 passes through lines 231 and 173 and 213 to contact 214, through theswitch L to line 215 to binding post C, through lines 216 and 218 tomagnet 134, through linesl 219, 220, 201, to contact strip ,108, throughbrush 117 to Contact strip 107, through lines,

203,202, 221 to point 138, then through lines 21.0, 180 and 181 tobinding post A, through lines 182 and 183 to battery. The magnet 134-bcing energized attracts the aruniturc 136, swinging the switch arin 113against the Contact 141 which closes the circuit to the motor asfollows: ("Jurrcnt from thtl hattery 171 Hows through the lines 231 and1721 to binding post B, through the line 207 to contact 141, through theswitch arm 143 to pivot 149, 243 through 242 to 214 to 247 to lines 246and 245 to motor, returning through the line 208 to pivot 1h18, throughthe switch arm 142 to Contact 138, through lines210 and 180 and 181 tohindingpost A, through the lines 182 and 183 to battery.

If the signal is already set at theleft and the turn is to be made to the right, the current will How asfollows: from the battery 171 through the lines and 173 to point, 195,to contact 190, through the lines 271` and 259 to binding post G,through line 260 to Contact 111, and through the` brush 118 now spanningthe interval 111 and 112 to line G1, through lines 262, 203 and 201 tomagr t 86, through lines 205, 200, 270 to 107, to lines 203, 202 and 221to point 138 through lines 210, 180 and 181 to binding post A, andthrough lines 182 and 183 to battery. This will energize the magnet 80releasing the spider and permitting thc brushes 118 and 117 to pass fromthc con tact-s 111 and 112 to the contact strips 10i' and 108. Thebridging of the interval be tween the contact strips 10.7 and 108 willenergize the magnet 133 as follows: From battery 171 the current willflow through the lines 231 and 173 to point 195 to contact 196, throughthe switch R to 107 and bindin post D, through line 198 to 1-1-5,`throng 200 to the "magnet 133, through line 201, to contact strip 108,across the brushes 117 and 118 to contact strip 107, through lines 203,202 vand 221 to point. 138, through Jines 210, 180 and 181 to bindingost A, through 182 and 183 t/b battery. I1`he energizin of the magnet133 attracts the armature 735, swinging the switch arm `1`42 intoengagement with` the contact 139 s0 that current will be supplied to themotor as follows: from the battery 171 through the lines 231 and 173 tobinding post through 207 to contact 141, across 150' to contact 139,-though switch arm 142 to 148, through line 208 to the motor, returningthrough lines 245 and 2h16 to point 247 to 211 through Q42 to 2113, 243to pivot 14.9 through 143 to 140 to 15:58, through line 210 to 180, 181to binding;r poet A, unil through lines 182 und 185i to huttm'y.

This rotation is continued until the pin 81 is en-`gaged by the letteh 83 and simultaneously the det-ent 70 is disengagedfrom the gear 60 by riding u` on the cani extremity of the core 77 ofth)j solenoid 79. The Spring 72 acting on the latch 72 engages thefinger 80 of the detent 70 and locks it in such opened position, wherebythe gear 06 and pinion ('35 are free to rotate under the continuedinoinentum of the motor, The current to the motor, however, is out ofi'at the inst unt when the (leteut 70 is disengaged` such cutting offbeing accomplished by the brush 117 run- Vning oil' of the Contactstrips 107 and 108 onto the contacts 113 and 114, as shown particularlyat Fig. 21. As the current supplied to energize the magnet 133 passesthrough the Contact strips 107, 108 and brush 117, it is obvious thatwhen the brush 117 passes off from the contact strips 108 and 107 thecircuit to themagnet 133 is broken Where by the armtubre 135 isreleased, thereby instantly breaking the circuit to the motor. As thisis all accomplished et the. instant when the detent engages the cam core77 it is obvious that the continued rotation of the motor will only beby its own momentum and that the current will cease to be su .plied tothe motor at that instant.

The fiction is the sinne, rotating the variousparts in the opposite direction until the brush 117 passes ofi of thestrips 107 and 108 onto the contacts 111 mul 112. ln this case the pin82 is engaged by the hitch 83` holding the soma phoro ut n lei'tlhorizontal position, the cutting out of the motor, the continued rota*tion of the parte under the momentum of the moving` motor1 being thesame, and the return to normal being the same either manu ally orautomatically.

Vhen the stop Signal is to be set the switch S is closed, energizing themagnet 133, but also energizing the magnet and the solenoid 79. Theenergizing of the solenoid 79 draws the core inwardly against thetension of. its spring, whereby the cam obstruction is removed and thespider conbeing mounted tinues to rotate until the detent is disengagedby engagement with the cam extremity 98 and the pin 95 has been engagedby the latch 93. It will be noted that the brush 118 is mounted adjacentthe brush 117, this being provided to span the interval between thestrips 107 and 108 on theione hand and 109 and 110 on the other hand sothat in setting the stop signal he brush 118 engages the strips 109 and0 before contact between 107 and 108 has b enbroken by the passing ofbrush 117 off of such strips, so that the magnet 133 continues to beexcited until the hrush 117 has passed through' one-half a revolutionofi of the strips 107 and 108and 109 and 110 successively onto thecontacts 115 and 116.

The releasing of the semaphore now set at vertical is similar to thereleasing of the semaphore when set at either right or left, hut isreleased only manually so that any desired turn of the steering wheelmay be made in the :ict of stopping without affecting or releasing thesignal set at stop When the switch 172 is closed the lights 99 and 100and the tell-tale li ht 168 are li hted and continued in lightecondition.

en a turn is made to the right the pin 127 carried by the spider 64closes the contact sprin 129 against the contact 131 and li hts tel-tale li ht 167. This lightsonly w en the motor llas actually y,turnedthe semaphore to right-hand signal sndidoes not light from simplyclosing the switch R. Likewise when the semaphore is actually turned toleft-hand position it closes thel 1 contact spring 12S against thecontact 130 and lights tell-tale ight 169.

j When the S switch is closed and the brush 124 engages the contactstrips 122, 123, the light 101 and the telLtalel7 li ht 170 are lighted,and remain in such lig ted condition so long as the semaphore is in stopposition. Inall of these cases it will be understood, of course, that assoon as the semahore is returned to normal the tell-tale ights, with theexception of 168, are extin-V guished and the rear li ht 101 is alsoextinguished. I t therefore ollows that the telltale at all times willshow the light '168 if the lights 99 and 100 are lilghted which, all inseries, wil be extinguished if either of such rear lights 99 and 100 areextinguished. Also the tell-tale light 170 bein in series with the rearlightlOl does not ight unless such rear light 101 lights, so that 4theoperator may at all times determine whether or not his lights areproperly lighted. By opening the switch 172 current to all the lights isinterrupted but the ine chanical and .electrical operation of themechanism is not aiiected.

It has also been explained that while current is being supplied tothemotor 51 the shunt to the bell 132 is always supplied with current sothat the operator may know whether or not his motor is o erati whollyasirde lfrom the use of the tell-talerlights.
